EVERETT I. RICHARDSON, OF LAWRENCE, MASSACHUSETTS.

EMPROVEIVEENT IN THE MANUFACTURE OF BOOTS AND. SHOES.

Specification forming part of Letters Patent No. 94,648, dated September 7, 1869.

To all whom it may concern Be it known that I, EVERETT l?. RICHARD- soN, of Lawrence, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in the Manufacture of Boots and Shoes; and that the following is a sufficiently full and exact description thereof to enable one skilled in the art to which my invention appertains to carry it into effect, reference being had to the accompanying drawings, which form part of this specilication.

My invention relates to that class of turned shoes or boots in which a welt is first attached to the sole, and then the upper sewed to the welt in a reversed condition, and afterward turned for finishing.

By this mode of construction channeling of the sole may be avoided, and though all the sewing may be performed by machinery, a shoe or boot so made possesses the good qualities and appearance of hand-made welted work.

In sewing the upper to the Welt by machinery in this manner, diiiiculty occurs in securing the entrance of the needle with certainty and precision by reason of the oblique position of the welt relatively to the path of the needle.

By my invention I so construct and apply the welt that the needle or other piercing-instrument may enter with precision and ease without danger of glancing; and in order that the said invention may be clearly understood, I will proceed to describe the same with reference to the accompanying drawings, in Which- Figure l is a plan view of a sole and welt prepared according to my invention and ready for the attachment of the upper or vamp. Figs. 2, 3, 4, 5, and 6 are fragmentary sections of connected portions of the sole, welt, and upper, illustrating. different modifications in the manner of preparing the welt. Fig. 7 is a transverse sectional view of the inished shoe or boot.

Similar letters of reference indicate corre spondin g parts in the several views.

A represents the sole, and B a welt attached thereto by stitches C, and extending around all that part of the sole which is exposed to wear.

A customary channel, a, may be formed around the shank andthe part where the heel is to be applied, so as to avoid the needless expense of applying a separate welt to parts of the sole which are not liable to wear.

b b represent channels, grooves, or notches formed in the edge of the welt to insure the proper entrance of theneedle or other piercinginstrument and prevent its glancing. These grooves may be formed in either of the ways represented in the several sectional views, Figs. 2, 3, 4, 5, and 6, or in any other substantially equivalent manner, and, if desired, an additional groove may be made in the edge or face to which the upper is to be attached, as shown at b in Figs. el and 6.

The welt B is attached to the sole A by sewing, as represented, or by nailing or any other equivalent or suitable means. If necessary or desirable, the inner edge of the welt may be fastened down by sewing, as shown at f in Fig. 6, or by nailing or other means, to prevent pulling up in wearing. When the welt has been properly attached its groove b will form, in connection with the channel a, a continuous channel, extending completely around the sole, but not made in the substance of the sole, excepting around the heel and shank portions, where no wear comes. The work may then be lasted inside out in any usual or proper manner, and the upper D secured to the welt B by stitches E, the position of the parts making it quite convenient to form the stitches, by machinery, with either a straight or curved needle, or other piercinginstrument, or by hand. This done, the shoe or boot may be turned and finished, with or without the addition of an insole o1' a second external sole, either or both, as the character of the work or other circumstances may render desirable. p

If preferred, notches or indentations of any shape, one for each stitch, may be formed in the inner edge or face of the welt, instead of or in addition to the groove b.

Having thus described my invention, what I claim, and. desire to secure by Letters Patent, channel a in the rear portion thereof, substan istially as described.

1. The notched 0rooved or channeled Welt l B, employed in theo manner and for the pur- EVERETT P RICHARDSON' pose substantially as herein set forth. Y Witnesses:

2. The combination of the Welt B, applied M. HARMON, to the front portion of the sole A, with the GEO. H. POOR.
